Led Outdoor String Lights Help With Christmas Lights?

Help with Christmas lights? - led outdoor string lights

Okay, so get that LED lamps are more energy and stuff, but I do not know how the mysterious radiation emitted. I like traditional bulbs larger than my father when I was a child. Although you can always find lights with incandescent lamps, they are all outdoors, and of course the need in the interior. However, I have seen replacement bulbs inside, and empty strings for the lights. My question is anyone knows where I can get one of these games? The other question is what the string inside or outside? Onions or chain?
